METAL TUBES, RODS; AND..THE LTKE.

Patented Jan. 30,1912.

To all whom it my concern Be it known that I, Fnnnnroo WERTH, a subject of the Emperor of Germany, res1d ing at 18 Corso Vercelli, Milan, in the Kingelectrolytes. This application refers to further improvements of the said apparatus;

It has been found, that the rings serving for the support of the tubes, rods or the like to be galvanized, may advantageously be constructed to be opened or open permanently as by this means the introduction of the tubes, rods or the like is greatly facilitated. To this purpose it would be sufficient to provide only a single chain or band with open rings, the tubes or the like being in this case firstly inserted in the closed rings of the other chain, whereafter in the open rings of the first named chain and at least the open rings closed and secured in some convenient manner.

The different figures of the drawings show the improved apparatus, as well as the various forms of chain, and another form of embodiment of the invention.

Figure 1 illustrates a cross section and Fig. 2 a partial longitudinal view of the apparatus with the improved holders. Fig. 3 shows a cross section and Fig. 4 a partial longitudinal view of another form of embodiment of the invention. Fig. 5 illustrates a side view of a bearing means for the apparatus form, as shown in Figs. 3 and 4:- Fig. 6 illustrates the forms of a closing device for open chain rings. Figs. 7, 8 9 illustrate views of different forms of open rings.

The form of rings or holders as illustrated in Figs. 1,"? and 9 is better adapted to certain cases, as it facilitates the replenishment of the apparatus with the articles to be treated. The rings or holders are entirely open outward; they are either forked or horseshoe shaped and their two arms -m are preferably bent inward, the curvature being suflici'ent toprevent the tubes or rods from leaving the, support even when the chain is running vertically.

' To prevent the articles to be galvanized from leaving the open rings and from falling out, when the chain is running in the lower curve and the openings of 'the'holders are directed downward, a suitably formed wooden block p is arranged in the tank beneath each of the chains, whereby the upper recessed periphery of this block lies closely around the-lower curve of the chain,

ings by the dotted lines. The blocks need only extend to the height at which the arms of the forked rings or holders reach the horizontal position whereupon the'tubes arms themselves. -The same result can be obtained by suspending a belt, band or the ables one to increase the number of tubes or rods to be supported on the same chain and therefore also the capacity of production.

. When desired the rings or holders may be provided with closing means Ha as shown in Fig. 6.

The form of supports or holders illus trated in Fig. 8 is suitable for tubes of large diameter; Each arm -m-- is fixed in convenient manner on every second chain member and can be removed or exchanged follow ing the diameter of the tubes without any difiiculty. The arms can be fixed also on each third or fourth chainmember. In every case the space between two arms can be closed by means of a little chain so that the belts ror the blocks ;0-

can be eliminated. The arms of the holders i can likewise be made straight or of any other desired form.

The construction of Fig. 9 shows anoth form of chain, whereby each holder is for with two arms, one of which is fixed on the as it is shown in the Fig. 1 of the drawor rods are again retained by the curved.

lltl

one on the right side of the neat on i left side of a chainmember and the other a, ieoiher; by this manner IUt; 11 goods change constantly L i. tact poin witli the supports, so that the limit on results perfectly.

"hould be noted that the tubes, rods or the like to be galvanized, still invariably reinai in electrical contact also when the chain carrying them reaches the lower curve, as owiw' to the rotary movement, the arms -m-- are in this position pressed. against the tubes or rods.

'lnother to ,n of embodiment of the in veution n 1; oo yen by the fact that the chains are suhst tuted through supports haying disk term, or similar rotation members, arranged in a'suitable manner on the shaft -w, as shown in Figs. 3, d and 5, said disks being provided with recess -sin which theends oi the rods or tubes are inserted. Such construct-ion allows likewise a constant loading of the bath tankowing to the .oility of substituting of the articles. To prevent'the going out or the rods or tubes from the said recess, during the passage through the lower curve the bat ltanlit provided. with halt-circular supports -g-, held by wooden blocks p-. 'llac) same result can evidently also be ob taincd by employing belts or hands as it is previously described and shown in Fig. 1.

The Fig. 5 of the drawing illustrates a View of a disk with different sizes of openings enabling one to load articles of difiei'ent dimensions.

l Vhat Ii claim and desire to secure by Lettors latent is:

1, In an apparatus for galvanizing metal tubes and the like, the combination of a tank having an electrolyte therein; a chainhaving its lower part passed into the electrolyte and having parts thereof vertically disposed, said ohain comprising links having laterally projecting arms having its upper and lower edges 0OI1CtV(-)(l; and means for retaining the arinsproject do A! w ,i tubes, irons and bill} the chains betweent tubes and the like b Lin dug; metal 1145 c inatlon of unng'. an olectroi, pairs oi: iets above t" electrol.
